Incorrect soil pH

Your blueberry shows stunted growth, interveinal leaf yellowing, and reduced yield. Soil pH outside the 4.5-5.5 range causes nutrient imbalances and iron deficiency. Plant in correct pH soil from the start. Monitor pH yearly; adjust with lime or sulfur as needed before planting. Use hydrangeas at field edges to monitor pH visually.

It is important to monitor and keep a record of soil pH on a yearly basis and take corrective actions if necessary. Plant hydrangeas at the end of blueberry rows to monitor soil pH.
